это исключение nullpointerexception произошло, когда я выполняю поиск по запросу searchView, здесь указан код, но я не вижу ничего подходящего 

private Context context = this;
private Toolbar toolbar;
RectF f;
private TextView title;
private ActionBar actionBar;
private RecyclerView searchRecyclerView;
private SearchView searchView;

    }

}

@Override

    return super.onOptionsItemSelected(item);
}

@Override

    if (movies.size() <= 0) {
        searchRecyclerView.setVisibility(View.GONE);
        loading.setVisibility(View.GONE);
        loading.stop();
        noDataContainer.setVisibility(View.VISIBLE);
    } else {

        loading.stop();
        searchRecyclerView.setVisibility(View.VISIBLE);
        adapter.setList(movies);
        adapter.notifyDataSetChanged();
    }
}

@Override
public void showLoading() {

}

@Override

}

@Override

здесь ведущий запрос 

private SearchContract contract;
private int pages = 1;
private String query = "";
private ArrayList<Movies> movieList = new ArrayList<>();
private int totalPage;

public MovieSearchPresenter(SearchContract contract) {
    this.contract = contract;
}

public void getMovieSearch(int pages, String query) {
    this.query = query;
    String url = EndPoints.SEARCH_BASE_URL + EndPoints.API_KEY + EndPoints.PAGES + String.valueOf(pages) + EndPoints.QUERY + query;
    Log.e("search_url", url);
    StringRequest request = new StringRequest(Request.Method.GET, url, response -> {
        Gson gson = new GsonBuilder()
                .setLenient()
                .create();
        MovieResponse movieResponse = gson.fromJson(response, MovieResponse.class);
        totalPage = movieResponse.getPage();
        movieList.addAll(movieResponse.getMovieList());
        contract.MovieSearchList(movieList);
    }, error -> contract.internetConnectionError(R.drawable.baseline_wifi_off_black_36));
    RequestQueue queue = Volley.newRequestQueue(MovieApp.getInstance().getApplicationContext());
    queue.add(request);
}

public int getTotalPage() {
    return totalPage;
}

public void increasePages() {
    pages++;
    getMovieSearch(pages, query);
}

и xml расположение кода
